POLYFLON™ M-532      
Polytetrafluoroethylene      
Product Description
POLYFLON PTFE M-series is a granular powder for compression molding. As melt viscosity is extremely high, it cannot be used for molding applied to general plastic. Therefore basically at first it is compressed in the mold and is fused by sintering over its melting point. Various molding methods are developed.
 
There are many types of POLYFLON PTFE to be applied the methods, conditions in mold processing and application.
 
Features
Good flowability, small particle size, sharp particle size distribution and low electrostatic charging property. Suited for thin-walled mold gap and iso static molding because of the excellent filling property.

Polymist® F284      
Polytetrafluoroethylene      
Product Description
Polymist® F284 is a white micronized PTFE powder composed of discrete particles.
Available worldwide, Polymist® F284 is a medium molecular weight grade with excellent thermal stability, designed for use in critical high temperature engineering and high perfomance polymers.
As with all Polymist® micronized powders, F284 offers excellent chemical and temperature resitence, low surface energy, low coeffcient of friction and good dispersion ability.
 
Main features of Polymist® F284 are:
 
Better wear resistance
 
Increased pressure x velocity (PV) limits
 
Reduced friction
 
Improved stick-slip response
 
Improved mold release

Storage and Handling
　
The usual precautions for safe storage and handling of Polymist® F284 should be taken according to material safety documentation and experience. There will be no chemical deterioration of the Polymist® F284 during proper storage.
　
　
Shelf life of Polymist® F284 micronized powders will vary depending upon whether the recommended storage conditions are maintained and whether the material remains free from foreign contamination during storage time (not exposed to dirt, dust, water or other chemicals). The material should remain sealed in the original containers and storage conditions should provide for protection from temperature extremes as well as rain, snow or other wet environments (or such conditions which may damage the storage containers in which the product is stored).
　
　
Safety and Toxicology
　
Before using Polymist® F284 PTFE micronized powders, consult the product Material Safety Data Sheet and follow all label directions and handling precautions.
　
As with all PTFE materials, handling and processing should only be carried out in well ventilated areas. Vapor extractor units should be installed above processing equipment. Fumes must not be inhaled and eye and skin contact ought to be avoided. In case of skin contact wash with soap and water. In case of eye contact flush with water immediately and seek medical help.
　
Do not smoke in areas contaminated with powder, vapor or fumes.
　
See Material Safety Data Sheet for detailed advice on waste disposal methods.
　
　
Packaging
　
Polymist® F284 is packaged in 25 kg nonreturnable drums. Each drum has two bag liners made of polyethylene resin.
